Objective: Traumatic brain injury (TBI) often occurs alongside injuries to other body regions, worsening patient outcomes. This study aimed to evaluate the impact of concomitant injuries on clinical outcomes in patients with isolated versus non-isolated TBI.
Method: A retrospective cross-sectional analysis was conducted using data from the Emergency Department-based Injury In-depth Surveillance System (EDIIS), encompassing 180,058 TBI patients admitted to 23 tertiary hospitals from January 1, 2020, to December 31, 2022.
